Technical description

Next AI Draw.io through 0.4.16 contains a server-side request forgery vulnerability in the POST /api/parse-url endpoint due to hostname validation that only checks string patterns without DNS resolution. Unauthenticated attackers can supply hostnames that bypass string validation but resolve to internal addresses, allowing them to reach arbitrary internal HTTP services and exfiltrate responses including cloud metadata.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
